BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

This invention relates generally to wireless communication systems andmore particularly to integrated circuits of transceivers operatingwithin such systems.

2. Description of Related Art

Communication systems are known to support wireless and wire linedcommunications between wireless and/or wire lined communication devices.Such communication systems range from national and/or internationalcellular telephone systems to the Internet to point-to-point in-homewireless networks. Each type of communication system is constructed, andhence operates, in accordance with one or more communication standards.For instance, wireless communication systems may operate in accordancewith one or more standards including, but not limited to, IEEE 802.11,Bluetooth, advanced mobile phone services (AMPS), digital AMPS, globalsystem for mobile communications (GSM), code division multiple access(CDMA), local multi-point distribution systems (LMDS),multi-channel-multi-point distribution systems (MMDS), radio frequencyidentification (RFID), Enhanced Data rates for GSM Evolution (EDGE),General Packet Radio Service (GPRS), and/or variations thereof.

Depending on the type of wireless communication system, a wirelesscommunication device, such as a cellular telephone, two-way radio,personal digital assistant (PDA), personal computer (PC), laptopcomputer, home entertainment equipment, RFID reader, RFID tag, et ceteracommunicates directly or indirectly with other wireless communicationdevices. For direct communications (also known as point-to-pointcommunications), the participating wireless communication devices tunetheir receivers and transmitters to the same channel or channels (e.g.,one of the plurality of radio frequency (RF) carriers of the wirelesscommunication system or a particular RF frequency for some systems) andcommunicate over that channel(s). For indirect wireless communications,each wireless communication device communicates directly with anassociated base station (e.g., for cellular services) and/or anassociated access point (e.g., for an in-home or in-building wirelessnetwork) via an assigned channel. To complete a communication connectionbetween the wireless communication devices, the associated base stationsand/or associated access points communicate with each other directly,via a system controller, via the public switch telephone network, viathe Internet, and/or via some other wide area network.

For each wireless communication device to participate in wirelesscommunications, it includes a built-in radio transceiver (i.e., receiverand transmitter) or is coupled to an associated radio transceiver (e.g.,a station for in-home and/or in-building wireless communicationnetworks, RF modem, etc.). As is known, the receiver is coupled to anantenna and includes a low noise amplifier, one or more intermediatefrequency stages, a filtering stage, and a data recovery stage. The lownoise amplifier receives inbound RF signals via the antenna andamplifies then. The one or more intermediate frequency stages mix theamplified RF signals with one or more local oscillations to convert theamplified RF signal into baseband signals or intermediate frequency (IF)signals. The filtering stage filters the baseband signals or the IFsignals to attenuate unwanted out of band signals to produce filteredsignals. The data recovery stage recovers raw data from the filteredsignals in accordance with the particular wireless communicationstandard.

As is also known, the transmitter includes a data modulation stage, oneor more intermediate frequency stages, and a power amplifier. The datamodulation stage converts raw data into baseband signals in accordancewith a particular wireless communication standard. The one or moreintermediate frequency stages mix the baseband signals with one or morelocal oscillations to produce RF signals. The power amplifier amplifiesthe RF signals prior to transmission via an antenna.

While transmitters generally include a data modulation stage, one ormore IF stages, and a power amplifier, the particular implementation ofthese elements is dependent upon the data modulation scheme of thestandard being supported by the transceiver. For example, if thebaseband modulation scheme is Gaussian Minimum Shift Keying (GMSK), thedata modulation stage functions to convert digital words into quadraturemodulation symbols, which have a constant amplitude and varying phases.The IF stage includes a phase locked loop (PLL) that generates anoscillation at a desired RF frequency, which is modulated based on thevarying phases produced by the data modulation stage. The phasemodulated RF signal is then amplified by the power amplifier inaccordance with a transmit power level setting to produce a phasemodulated RF signal.

As another example, if the data modulation scheme is 8-PSK (phase shiftkeying), the data modulation stage functions to convert digital wordsinto symbols having varying amplitudes and varying phases. The IF stageincludes a phase locked loop (PLL) that generates an oscillation at adesired RF frequency, which is modulated based on the varying phasesproduced by the data modulation stage. The phase modulated RF signal isthen amplified by the power amplifier in accordance with the varyingamplitudes to produce a phase and amplitude modulated RF signal.

As the desire for wireless communication devices to support multiplestandards continues, recent trends include the desire to integrate morefunctions on to a single chip. However, such desires have goneunrealized when it comes to implementing baseband and RF on the samechip for multiple wireless communication standards.

Therefore, a need exists for an integrated circuit (IC) that implementsbaseband and RF of multiple wireless communication standards on the sameIC die.

FIG. 16 is a schematic block diagram of another embodiment of a VoiceData RF IC 70 includes the data RF section 236, the voice RF section238, the interface module 234, the voice baseband processing module 230,the data baseband processing module 232, the AHB bus matrix 94, themicroprocessor core 190, the memory interface 90, and one or more of aplurality of interface modules. The plurality of interface modulesincludes the mobile industry processor interface (MIPI) interface 192,the universal serial bus (USB) interface 194, the secure digitalinput/output (SDIO) interface 132, the I2S interface 196, the UniversalAsynchronous Receiver-Transmitter (UART) interface 198, the SerialPeripheral Interface (SPI) interface 200, the power management (PM)interface 124, the universal subscriber identity module (USIM) interface120, the camera interface 156, the pulse code modulation (PCM) interface202, the video codec 204, the second display interface 126, thecoprocessor interface 136, the WLAN interface 140, the Bluetoothinterface 146, the FM interface 150, the GPS interface 152, thecamcorder interface 160, and the TV interface 164.

FIG. 17 is a schematic block diagram of an embodiment of a voice RFsection 238 that includes a receiver section 270 and a transmittersection 272. The receiver section is coupled to convert the inbound RFvoice signal 258 into the inbound symbol stream 260.

The transmitter section 272 includes a conversion module 274, amodulation parameter module 276, 1^(st) up-conversion module 278, a2^(nd) up-conversion module 280, a combining module 282, and a poweramplifier circuit 284. The power amplifier circuit 284 may include oneor more power amplifier drivers coupled in series and/or in paralleland/or one or more power amplifiers coupled in series and/or inparallel.

In operation, the conversion module 274 and the modulation parametermodule 276 receive the outbound voice symbol stream 254, where eachsymbol is expressed as a hybrid coordinate having an in-phase componentand a quadrature component. The conversion module 274 converts thein-phase component and the quadrature component of a symbol into anormalized I symbol 286 and a normalized Q symbol 288. This may be doneby setting the amplitude of the in-phase component and the quadraturecomponent of the symbol to the same value. For example, the in-phasecomponent is A_(I) sin(ω_(d)(t)) and the quadrature component is A_(Q)cos(ω_(d)(t)), where A_(I) and A_(Q) are the amplitudes of the in-phaseand quadrature components, respectively. By setting the amplitudes A_(I)and A_(Q) to the same value (e.g., 1 or A₀), then the normalized Isymbol 286 would be sin(ω_(d)(t)) and the normalized Q symbol 288 wouldbe cos(ω_(d)(t)).

The modulation parameter module 276 generates offset information 290 andtransmit property information 292 from the outbound voice symbol stream254. In one embodiment, the offset information 290 corresponds to phaseinformation of the symbol (e.g., Φ(t)), which may be calculated astan−1(A_(Q)/A_(I)). Alternatively, the offset information 290 maycorrespond to frequency information of the symbol.

The modulation parameter module 276 generates the transmit propertyinformation 292 as a power level setting or as amplitude modulationinformation. For example, if the data modulation scheme uses phasemodulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequencyshift keying) without amplitude modulation, then the transmit propertyinformation 292 would correspond to the power level setting. In thealternative to the modulation parameter module 276 generating the powerlevel setting, the voice baseband processing module 230 may generate it.

If the data modulation scheme using both phase and amplitude modulation(e.g., 8-PSK, QAM) or both frequency and amplitude modulation, then themodulation parameter module 276 would generate the amplitudeinformation. In one embodiment, the amplitude information (e.g., A(t))is generated as the square root of (A_(I) ²+A_(Q) ²).

The 1^(st) up-conversion module 278 combines the normalized I symbol 286with the offset information 290 to produce an offset normalized I symbol286 (e.g., sin(ω_(d)(t)+Φ(t)). This signal is mixed with an in-phaselocal oscillation that has a frequency corresponding to the secondfrequency band (e.g., 1920-1980 MHz) to produce a 1^(st) up-convertedsignal 296 (e.g., ½ cos(ω_(RF)(t)−ω_(d)(t)−Φ(t))−½cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))). The 2^(nd) up-conversion module 280combines the normalized Q symbol 288 with the offset information 290 toproduce an offset normalized Q symbol 288 (e.g., cos(ω_(d)(t)+Φ(t)).This signal is mixed with a quadrature local oscillation that has afrequency corresponding to the second frequency band and filtered toproduce the 2^(nd) up-converted signal 298 (e.g., ½cos(ω_(RF)(t)−ω_(d)(t)−Φ(t))−½ cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))). Thecombining module 282 combines the first and second up-converted signals296 and 298 to produce an RF signal 300 (e.g.,cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))).

The power amplifier circuit 284 amplifies the RF signal 300 inaccordance with the transmit property information 292. In oneembodiment, the transmit property information 292 is a power levelsetting (e.g., A_(P)) such that the outbound RF voice signal 256 may beexpressed as A_(P)*cos(ω_(RF)(t)+ω_(d)(t)+Φ(t)). In another embodiment,the transmit property information 292 is the amplitude information(e.g., A(t)) such that the outbound RF voice signal 256 may be expressedas A(t)*cos(ω_(RF)(t)+ω_(d)(t)+Φ(t)).

FIG. 18 is a schematic block diagram of an embodiment of a data RFsection 236 that includes a receiver section 310 and a transmittersection 312. The receiver section 310 is coupled to convert the inboundRF data signal 246 into the inbound symbol stream 248.

The transmitter section 312 includes a conversion module 314, amodulation parameter module 316, 1^(st) up-conversion module 318, a2^(nd) up-conversion module 320, a combining module 322, and a poweramplifier circuit 324. The power amplifier circuit 324 may include oneor more power amplifier drivers coupled in series and/or in paralleland/or one or more power amplifiers coupled in series and/or inparallel.

In operation, the conversion module 314 and the modulation parametermodule 316 receive the outbound data symbol stream 242, where eachsymbol is expressed as a hybrid coordinate having an in-phase componentand a quadrature component. The conversion module 314 converts thein-phase component and the quadrature component of a symbol into anormalized I symbol 326 and a normalized Q symbol 328. This may be doneby setting the amplitude of the in-phase component and the quadraturecomponent of the symbol to the same value. For example, the in-phasecomponent is A_(I) sin(ω_(d)(t)) and the quadrature component is A_(Q)cos(ω_(d)(t)), where A_(I) and A_(Q) are the amplitudes of the in-phaseand quadrature components, respectively. By setting the amplitudes A_(I)and A_(Q) to the same value (e.g., 1 or A₀), then the normalized Isymbol 326 would be sin(ω_(d)(t)) and the normalized Q symbol 328 wouldbe cos(ω_(d)(t)).

The modulation parameter module 316 generates offset information 330 andtransmit property information 332 from the outbound data symbol stream242. In one embodiment, the offset information 330 corresponds to phaseinformation of the symbol (e.g., Φ(t)), which may be calculated astan−1(A_(Q)/A_(I)). Alternatively, the offset information 330 maycorrespond to frequency information of the symbol.

The modulation parameter module 316 generates the transmit propertyinformation 332 as a power level setting or as amplitude modulationinformation. For example, if the data modulation scheme uses phasemodulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequencyshift keying) without amplitude modulation, then the transmit propertyinformation 332 would correspond to the power level setting. As analternative, the data baseband processing module 232 may generate thepower level setting.

If the data modulation scheme using both phase and amplitude modulation(e.g., 8-PSK, QAM) or both frequency and amplitude modulation, then themodulation parameter module 316 would generate the amplitudeinformation. In one embodiment, the amplitude information (e.g., A(t))is generated as the square root of (A_(I) ²+A_(Q) ²).

The 1^(st) up-conversion module 318 combines the normalized I symbol 326with the offset information 330 to produce an offset normalized I symbol(e.g., sin(ω_(d)(t)+Φ(t)) 326. This signal is mixed with an in-phaselocal oscillation 294 that has a frequency corresponding to the firstfrequency band (e.g., 890-915 MHz) to produce a 1^(st) up-convertedsignal 336 (e.g., ½ cos(ω_(RF)(t)−ω_(d)(t)−Φ(t))−½cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))). The 2^(nd) up-conversion module 320combines the normalized Q symbol 328 with the offset information 330 toproduce an offset normalized Q symbol (e.g., cos(ω_(d)(t)+Φ(t)). Thissignal is mixed with a quadrature local oscillation 294 that has afrequency corresponding to the first frequency band and filtered toproduce the 2^(nd) up-converted signal 338 (e.g., ½cos(ω_(RF)(t)−ω_(d)(t)−Φ(t))+½ cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))). Thecombining module 322 combines the first and second up-converted signals336 and 338 to produce an RF signal 340 (e.g.,cos(ω_(RF)(t)+ω_(d)(t)+Φ(t))).

The power amplifier circuit 324 amplifies the RF signal 340 inaccordance with the transmit property information 332. In oneembodiment, the transmit property information 332 is a power levelsetting (e.g., A_(P)) such that the outbound RF data signal 244 may beexpressed as A_(P)*cos(ω_(RF)(t)+ω_(d)(t)+Φ(t)). In another embodiment,the transmit property information 332 is the amplitude information(e.g., A(t)) such that the outbound RF data signal 244 may be expressedas A(t)*cos(ω_(RF)(t)+ω_(d)(t)+Φ(t)).

In these embodiments,the RF section 372 modulates a local oscillator based on phaseinformation of the outbound voice symbol stream 254 to produce a phasemodulated RF signal. The RF section 372 then amplifies the phasemodulated RF signal in accordance with amplitude information of theoutbound voice symbol stream 254 to produce the outbound RF voice signal256. Alternatively, the RF section 372 may amplify the phase modulatedRF signal in accordance with a power level setting to produce theoutbound RF voice signal 256.

For incoming voice signals, the RF section 372 converts the inbound RFvoice signal 258, which has a carrier frequency in the second frequencyband (e.g., 2110-2170 MHz) into an inbound voice symbol stream 260.
